Under full throttle acceleration while merging onto highway the car would not deliver power and the check engine started flashing. Pressing the accelerator did not make the car go. I had to pull over and stop the car. I turned it off and turned it back on and was able to drive away. Both times, the weather was very humid and I was merging on a ramp that had an uphill incline. This happened twice within a few days. The first time was on 3-MAY-2025 and the second time was on 5-MAY-2025
